Preheat your oven: to 180°C/400°F/gas 6.
Spinach: add the fresh spinach leaves to the bowl of a food processor and blitz to finely chop.
Cob loaf: place the cob loaf into the centre of a chopping board and use a serrated knife to cut the top off. Then trace a circle in the top of the dip with a small knife. Next remove the soft white bread from the circle to create a hole for the dip to go into.
Bread pieces: cut the top of the cob loaf and the bread you removed from the centre of the cob loaf into small pieces. Give these a liberal spray with cooking oil and set aside for now.
Combine: next add the cream cheese, Greek yogurt and French onion soup mixture to the chopped spinach and blitz to combine. Then use a spatula to scrape down the insides of the food processor bowl and again blitz to combine.
Dip into bread: use a spatula to transfer the combined spinach dip into the hole in the cob loaf.
Oven bake: place the filled cob loaf onto a silicon mat on a baking tray. Then place the chopped additional bread pieces next to it. Place the baking tray into the oven on the middle shelf. After 10 minutes use oven mitts to remove the tray and transfer the toasted bread pieces to a serving plate. Then remove the dip to the oven and bake for a further 20 minutes.
To serve: place the spinach cob loaf into the centre of a serving platter and surround the base with a combination of toasted bread pieces, celery sticks, carrot sticks, cherry tomatoes and snap peas.
